Y-Chromosome Studies

Single nucleotide polymorphism is a common, but minute, variation that occurs in human DNA at a frequency of one every 1,000 bases, often used to track inheritance.SNP in DYS199 The place on a chromosome where a specific gene is located, a kind of address for the gene.locus present in all 5 Native American populations

Examination
of more than 2,500 Y-chromosomes of wide geographic origin

and Asian populations (not found in African, Australoid, or
Caucasian European populations)

The Y-chromosome is found only in males (the
normal male has one X- and one Y-chromosome). Therefore Y-chromosomes are
transferred from father to son, without recombination. Any A permanent structural alteration in DNA, consisting of either a substitution, insertion or deletion of nucleotide bases.mutation introduced into the Y-chromosome will be transferred to descendant males.

in the Y-chromosome is
found in all 5 Native American populations and Asian populations (native
Siberian populations, Siberian Eskimos, and Asian Chukchi), but not in
African, Australoid, or Caucasian populations.1
These studies show that all Native American populations are related to
Asian populations.
